Product Overview
The FUJIKIN 796-029684-321 / FBDCL-AD01-6.35X2C-2B3-316LP-KDY is a high-purity, pneumatically actuated diaphragm valve engineered by FUJIKIN, a global leader in precision fluid control technology. Operating on a linear diaphragm actuation principle, this valve isolates the process media from the actuator mechanism via a flexible diaphragm, eliminating packing, stem seals, and dead volume. The model designation FBDCL-AD01-6.35X2C-2B3-316LP-KDY indicates a 6.35 mm (1/4 in) line size with a 316L stainless steel body and a KDY-series pneumatic actuator, making it ideally suited for ultra-clean, corrosive, or high-purity gas and liquid service in semiconductor, pharmaceutical, and advanced industrial process systems.

Engineering Features & Advantages
- Precision Performance: The diaphragm isolation design provides exceptional flow control with zero stem leakage and minimal dead volume, ensuring high-purity media integrity and repeatable metering in critical process lines.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a 316L stainless steel body offering superior corrosion resistance and long diaphragm service life under cyclic pneumatic actuation.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement for FUJIKIN FBDCL-series diaphragm valves without modification to existing manifolds or tubing.
- Contamination-Free Operation: The absence of sliding seals and packing eliminates particle generation and fluid entrapment, making it ideal for high-purity and sterile applications.
Typical Industrial Applications
This FUJIKIN diaphragm valve is widely deployed in semiconductor fabrication equipment for high-purity gas and chemical delivery, pharmaceutical and bioprocessing systems requiring sterile flow paths, analytical instrumentation
